GBC Pro, with reset problems

As you have already noticed, GBC games are one of the best choices for android gaming, the thing is...their emulators aren't perfect.
GBC Pro is...guess what, a GBC emulator. I paid, downloaded and installed it, the problem is, when pressing the d-pad and the A-B buttons, the rom is resetted. Every time. It's annoying enough to be posted. Did anyone have this problem, and solved it?
My device (Philips Connect 3) has no physical button avaliable to the emulator, so the touchscreen is the only input source.
